| dc.description | We investigate the $B \to K^{*}π$ decays, one of hardly understandable processes among charmless B-meson decays, within the perturbative QCD method. Owing to the dynamically enhanced mechanism in PQCD, we obtain large branching ratios and large direct CP asymmetries, for instance, $Br(B^0 \to K^{*\pm}π^{\mp})=(9.1^{+4.9+0.3}_{-3.9-0.2})\times 10^{-6}$, $Br(B^{\pm} \to K^{*0}π^{\pm})=(10.0^{+5.3}_{-3.5}\pm 0.0)\times 10^{-6}$; $Acp(B^0 \to K^{*\pm}π^{\mp})=(-19.2^{+0.5}_{-1.7})%$, and $Acp(B^{\pm} \to K^{*\pm}π^{0})=(-43.7^{+4.0}_{-4.2})%$. The branching ratios are consistent with experimental data and large direct CP violation effects will be tested by near future experimental measurements in Asymmetric B-factory. | |
